To all whom it may concern.-

Beit known that I, SAMUEL G. Gossa citizen of the United States, residing at Chicago,

in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Folding-Machines, of which the following is a specification reference being had to the accompanying drawings.

' My invention relates particularly to irnprovements in the former or V-shapedinternal guide over which a web of a er is folded longitudinally on the run with he coperation of a pair of folding-rollers at its apex; and the object is to prevent the smutting or offsetting of the print upon the paper as it passes over the former.

To that end lmy invention generally described, consists in forming th V-shaped'former or internal guide `of a pair of converging rollers, preferably spindleshaped, journaled at their upper ends 1n suitable bearings and at their lower ends in suitable bearings a short distance above the lower end or apex of the former and so placed that the outer sides 'of these rollers form, with the point or apex of the former, the sides of the complete V-shaped internal guide over which the paper is folded by meansof the usual folding-rollers below the a ex of the former. These rollers are rotate very slowly in comparison with the surface speed of the paper and are supplied ata suitable part of their surface away from the part contacted by the paper with a sufficient supply of oil to prevent. the smutting or offsetting of the ink on'the surface of the webs next to the former as the webs pass over them.

In the drawings, Figure 1 is a front elevation of a former with part of the plate broken away. Fi 2 is an enlarged side elevation of the devices shown in Fig. 1. `Fi 3 is an enlarged detail being a view of t e lower portion of the former with the late broken away tov show the way in whic the rollers formin the side edges of the former are journa ed at their lower ends; and Fi 4 is a detail, being a section online 4 4 of Fig. 1.

Referring to the drawings, 5 6 indicate portions of the folder-frame.

7 indicates a shaft upon which is mounted a roller 8.' The shaft 7 is journaled in the usual manner in the .folder-frame 'and is driven in the usual manner. In Fig. 2 gears e sides of this,

9 10 are shown as indicating driving mechanism for the shaft 7.

11 indicates a -V-sliaped internal guide orl their lower-en s-which are journaled near their upper ends in su ports 17 17, secured to the former 1 1, and at t eir lower ends are journaled, as is best shown in detail Fig. 3 in suitable bearin s just above the point 15 of the former. T ese rollers 16 are so vlocated and sha ed that they form, with the sides of the fol -marking point 15, the outside edges of the V-shaped former, over which the paper travels in Abeing folded longitudinally on the run.

The shape of the former, therefore, as will be l seen, with these rollers forming the outer edges of the internal guide` or support over which the paper runs, is substantially the same as the well-known Mslmaped internal guide or former.

18 indicates the usual fold-la lng rollers between which the paper is folde and which cooperate with the former 11 to give the paper its longitudinal fold in the usua manner.

19 indicates castings, which are supported upon the folder-frame 6 behind the former 1 1 20 indicates wormears which are secured upon the upper ends o the rollers 16.

21 indicates worm-gears which aremounted upon stop-shafts 22 and which engage the worm-gears 20. The stop-shafts 22 are journaled in suitable bearings 23, which are supported upon the castings 19.

24 (see Fig. 2) indicates worm-gears which are secured upon the inner end of the stop-` shaft 22.

25 (see Fig. 1) indicates wormears which are secured to shafts 26 and'whic mesh with the worm-gears 24.. The shafts 26 are jour- IOO 2O y toward the bottom an are covered over the y Fig. 1, are inged at their inside edges byv lhinges to the plates '14, so that they maybe turned up to ex oses the absorbent material below, herona r described. llt will of course be understood that the hin es 30 are sun-k'in the plates, so that the Who'e surface n of the plates 14 and 14 may be flush and smooth topermi-t the paper to run over the former in the usual manner.

Referring particularly to the detail in Fig.. s `31 indicates a box open at its outer eolie, W ich-is'placed underneath the surface 'o' t' e 'former 1 I and upon 'each side thereof. y'lllfrese boxes, 'as is shown in dotted lines in Fig. 1,

converge from the up er part 'of the iormer tog by the hinged plates 14a.

v 2 indicates absorbent material adapted to becomesaturated With an suitable oil and located in 'the boxes 31. e absorbent ma- ,terial '32 is preferably formed of 'a strip .of -heavy felt shaped to ``t the boxes 3i and projecting beyon the outer edges of' the boxes .l n 31,80 as 'to bear upon the inside surface oi the 3Q y also be seen articular'ly b ithe broken-away rdl'le'rs 136, as is 'best shown in Fig. 4i, as may olf-tion 'in ig. '1.y 'The 'a sorbent material 2 being saturated With any suitable` oil 'or similar materiahfit will 'be vobvious that as the rollers '1"6 slowly revolve 'their surface be given 'a slight 'coating vof oil which is too small 'to 'in any Way injure tine paper as it passes over the former on the'run, but Which will4 reven't any smu'tting or yoisettingof the irilr While 'the paper is -being folded.

. The absorbent material may "be su plied with oil in any suitable Way-snch, l or instance, 'as by pipes 33 33 ,Which :lead from any suitable source of su A ly (not shown) an open'at their inneren s to the absorbent material 32 near the top.

Any suitable oil maybe used, suoli Vas a paraiifineoil or a :mixture oi paraffin-oil Aand macine-'oil lor a suitable mixture of 'kerosene and machine-oil. l

Any suitable 'material operating in the same'manneras'an 'oilfstrrct -so called, to prevent the sm'utting or odisettrn of the ink may of course be used. I there ore ldo not conine'myseifzto the use df, oi-1, lstrictly so called, :but use 4the term forjconvenience 'as 2a generic one indicating either :an 1oil `or any similar substance having a like eiect in preventing the -smutting vor vvofiset't'ingof the nik. As the rotation of therollers 16 is very slow, they may be rotated in either direction.

combination with a former, of converging rollers journaled on said former and forming the sides thereof, means for rotating said rollers at a surface speed slow relatively to that of the paper to be. folded, and an oiled absorbent material bearing against said rollers.`
